What is the exact error message you get?

thanks for reply

I got an error that can not connect to mysql database ..

it means the connection could not be opened ..

i define a connection string as

$link=mysql_connect("",$userid,$passwd);

i am not giving a hostname , i think it will take a local host name automatically .
should i make request to isp server to give their name ? or what should i do ?

You should always user the hostname, either 'localhost' or the real hostname.

... or 127.0.0.1 , it works even is the localhost name is not localhost 8D ...
